Description
Technical field
The present invention relates to lighting technical field, more particularly to LED light source technical field specifically refers to a kind of high aobvious refer to color high
Warm LED light source and its manufacture method.
Background technology
Phosphor powder is excited to mix the method for generally using that white light is current white light LEDs that sends with blue-ray LED, selection is not
With the phosphor powder of kind, adjusting the thickness of fluorescent powder coating can be made the white light source of different nominal colour temperatures, form nominal color
Temperature series of products from low to high.These white light LEDs products also can meet general lighting requirement in terms of colour rendering.
The high-quality low color temperature white light LED of common nominal below colour temperature 5000K on Vehicles Collected from Market, its general colour rendering index Ra oneself through can be with
Reach more than 90.But nominal colour temperature can only achieve higher than the existing LED product of this scope, its colour rendering (general colour rendering index Ra)
85 is even lower.As general lighting, due to seldom using the LED light source of nominal more than colour temperature 5000K, thus with existing
LED product replaces existing electricity-saving lamp and fluorescent lamp illumination, and its colour rendering level can meet requirement.
But in many industrial and agricultural products production processes, it is desirable to which the apparent colour of product is controlled and checked, this
Inspection work is planted to want Bian using the application specific standard light source of strict high-color rendering (at least general colour rendering index Ra ＞ 92) to illuminate.
And the nominal colour temperature of common inspection application specific standard light source is all higher.The most frequently used has D65 and D75 standard sources, and its is nominal
Colour temperature is respectively 6500K and 7500K.Because the high color temperature LED product of in the market far can not meet the colour rendering of standard sources
It is required that (requirement of general colour rendering index Ra ＞ 92), these inspection light sources for being used in industrial and agricultural production testing department at present, all
Or extraordinary high aobvious fluorescent lamp can only be used, it is domestic some require inspection laboratory use high this kind of fluorescent tube also to rely on into
Mouthful, expensive, maintaining high cost.
Additionally, in the colourity inspection of industrial products, white or whiteness inspection are the most universal.For whiteness inspection,
In addition to general colour rendering index Ra, the special colour rendering index R10 of lighting source is also the important finger for evaluating color rendering properties of light source
Mark.But due to the limitation of process materials, existing aobvious fluorescent lamp high is also difficult to produce the product of Ra and R10 all higher than 92.
The deficiency that the present invention exists aiming at the high-color rendering light source of current trial, a kind of solution of proposition.
For in theory, it can be the colour rendering for improving light source that Bian is carried out mixing complementation with the LED of several different colours,
But use which color and the LED and the respective ratio with how many luminous flux of how many nominal colour temperatures to be mixed, it is possible to
The high color temperature LED light product-derived of required high-color rendering is obtained, have to instruct to improve the simple of colour rendering can for non-See so far
Capable color matching theory and method.Therefore, in the market is so far there are no D65, D75 standard sources of general colour rendering index Ra ＞ 92 go out
